A restrictive VSD is a small size of the defect, it doesn’t cause any symptoms and often closes on it owns as the person grows (“Ventricular Septal Defect (VSD)”). Medium VSD’s causes symptoms during infancy and childhood; it is also unlikely to close on its own (“Ventricular Septal Defect (VSD)”). If the defect is large, it is called a nonrestrictive VSD. It may become smaller as the person grows, but a surgery is usually required for it to close on its own (“Ventricular Septal Defect (VSD)”).
If a nonrestrictive VSD is not closed, the most common complication is heart failure. Heart failure is caused by the increased work and energy required of the body (“Ventricular Septal Defect (VSD)”. If a child is difficult to feed and shows lack of growth, these are some symptoms of heart failure (“Ventricular Septal Defect (VSD)”). Infective endocartis, bacterial infection, pulmonary hypertension, high blood pressure in lungs, aortic insufficiency are examples of possible complications after surgery (“Ventricular Septal
